Introduction of Methods to Prevent Oxidation of Rubber Cable Conductors

The general rubber cable is a kind of conductive copper core with five types of copper conductors. 

In the production process, the copper conductor is often oxidized and discolored, which seriously affects the quality of the product and has become a difficult technical problem for many cable manufacturers in China. 

In principle, metal copper for cables mainly has physical methods to block copper from contact with humid air, cathodic protection redox method to prevent oxidation of copper conductors, chemical methods to form a passivation film on the surface of copper conductors to prevent oxidation, or to spray special liquid on the surface of conductors. 

Take the production of general rubber cable as an example, the main method of anti-oxidation control in each process.

Transportation, testing, and storage of copper rods before entering the factory

Most cable companies in China use copper for outsourcing. 

They should choose high-quality metal copper rods to regulate the transportation and delivery processes and systems of suppliers. 

The copper rods are inspected according to GB/T 3048.2 or cable enterprises. 

The storage of the copper rods can be covered with plastic or plastic film, ie the simplest physical barrier prevents the copper rods from coming into contact with moist air. 

When using copper rods in the workshop, it is necessary to perform a visual inspection of the copper rods one by one to see if there is blackening, and control from the source of production.
